Expression levels of lipoyltransferase 1 (LIPT1), dihydrolipoamide S-Acetyltransferase (DLAT), metal-regulatory transcription factor 1 (MTF1), glutaminase (GLS), and cyclin dependent kinase inhibitor 2 A (CDKN2A) genes were higher in HCC patients [105, 106]. This evidence concerns the gene GLS and hepatocellular carcinoma.
